The hactivists kept pounding away at the wall and Chinese today have found holes to dart through. New software, such as Dynaweb's 'Dongtai' and Ultrareach's 'Roaming without Borders', can be easily downloaded in China, allowing users to surf freely. 'Everyone is using it,' says one writer, who believes Chinese are openly passing the programs around. 'And the government can't trace the internet provider's address.' She says the software is continuously getting better.

Still, sophisticated Chinese users report that it takes only some will and creativity to freely travel the Internet, thanks partly to Mr. Xia and other digital liberators. At the same time, he's sober about the forces amassed against him and very cautious about overtly declaring any set political agenda. "All we want is for information to freely flow," Mr. Xia says, "so that people have a fair chance to make their choices." (Robert Benjamin report)

Bill Xia left China for the US in the late 1990s. He keeps up with events in his homeland, mostly online.

He has been amazed by the rapidly growing number of people in China who can join him in cyberspace.

But he has also watched as Beijing tries to keep tighter and tighter control over those Chinese web users.

Mr Xia says he got fed up with the way the Chinese authorities control access to information on the web

"I started realising the media controls in China. And then I realised the internet presented a great opportunity to get around those media controls," he said.

In 2001, Mr Xia and some other US-based volunteers started Dynamic Internet Technology.

The company helps Chinese web users get around China's firewall.

The authorities have recently started arresting people for posting what it deems negative articles on overseas websites. Frank Lu of the Hong Kong-based Information Centre for Human Rights and Democracy said that “You no longer even need to be an activist; just posting your own article is enough. Fourteen Internet essay writers have been arrested, sentenced or denied appeal since mid-October 2003.

Add to this, the Government's increasing use of technology to block and divert users away from areas it considers sensitive. Bill Xia, President of U.S. company Dynamic Internet Technology said, "With new technology, they are upgrading their system within a couple of months, though they probably have to go through approvals, I'm rather impressed by their speed.”

With new technology, they're now upgrading their system within a couple of months," said Bill Xia, president of Dynamic Internet Technology, a U.S. company that develops technology to circumvent China's filters. "They probably have to go through approvals, but I'm rather impressed by their speed.

What do DIT Inc. analysts think of the Berkman study?
This study provides by far the most comprehensive study of internet blockage in China about publicly available documents.

Would you say that the Berkman data matches DIT Inc's empirical analysis of China's filters?
What they described in the technical appendix is consistent with what we observe - except dynamic blocking that might affect his results. In certian senario, unrelated sites will be unaccessible for a while after the connection/computer used for testing trigger the blocking for keyword etc.

The Berkman data makes it clear that while filtering is evolving, on some levels it remains quite crude, often inadvertently blocking information for no apparent reason . .
. . Right! For the list found out, it is not surprising that some "innocent" sites are blocked as well. Their policy is to "kill 1000 innocent rather than miss one". They made mistake as well. When China first launched the DNS hijacking, dailynews.sina.com.cn and minpao.com was mistakenly hijakced as well (even now). (AP reported it as possible hacking from Falun Gong, which is not true. AP 's report came after my report. Sorry they didn't take our analysis.)

Using Freenet-China, software created this year, people in China have been able to get to banned sites and documents, including government documents on the Tiananmen Square massacre, and Web sites for the outlawed religious movement Falun Gong, according to Bill Xia, president and founder of Dynamic Internet Technology. Xia, a Chinese immigrant, said the company's focus is developing software to get around Chinese government censorship.

With 30,000 Net police specializing in Net censorship, the People’s Republic of China has developed the largest and most sophisticated IP blocking and content filtering system in the world, said Bill Xia, president of Dynamic Internet Technology at a November 4 Congressional-Executive Commission on China (CECC) roundtable.

DIT's DynaWeb is a proxy network launched in March this year to help Chinese users both download banned documents and other proscribed material, and reach Net sites blocked by the Chinese authorities.

Available at dwang.orgdns.org, it makes it tough for Chinese servers to identify users and makes it just as hard for PRC Net cops to block it because although its Web address stays the same, its IP frequently changes. 
......
DIT spokesman Bill Dong told p2pnet.net, "Now, it is clear that China has put domain name hijacking as their major way to block dissident sites. They are able to block a domain name within one day."

At the end of September, DynaWeb domain names were hijacked to a fixed IP 64.33.88.161 in China, along with other sites such as Voice of America's www.voa.gov. Dong wrote a detailed report on this hijacking.

Bill Xia is a Chinese immigrant to the United States and president of Dynamic Internet Technology, a small U.S.-based company that provides technical services to help get Chinese-language e-mail to people in China. Mr. Xia says the Internet is increasingly becoming a factor in Chinese government harassment and arrest of dissidents. "Last year, there were more than 10 arrests in China for distributing forbidden information," said Bill Xia. "This will create fear among the public. For the general public in China, they are now gradually realizing the existence of censorship consciously."
Mr. Xia says he believes the Chinese government has more than 30,000 employees who specialize in Internet censorship.

IF SOME LAWMAKERS in the United States get their way, freedom-promoting computer hackers may soon receive a bucketful of money to battle China's Internet-censoring police.
......
Dynaweb, was launched in North Carolina in March by a group of Chinese-American engineers keen to open up the Internet to users in China. Dynaweb, which helps Chinese users access blocked Internet sites and download banned documents, is difficult for Beijing to attack because it regularly changes its numerical Internet Portal address, which the government uses to identify sites. Company spokesman Bill Dong says they would use any money provided by Cox's legislation to "expand our server, make our performance better and respond to any technology China develops to stop us."

WASHINGTON -- While the Great Wall no longer deters would-be invaders from entering China, experts meeting in Washington on Monday said the Chinese government continues to maintain a nearly rock-solid cyberwall.

"China has developed the largest and most sophisticated IP-blocking and content-filtering system in the world," said Bill Xia, president of Asheville, North Carolina-based Dynamic Internet Technology. The company's DynaWeb product, launched in March, attempts to skirt Chinese Internet censorship.

Dynamic Internet Technology, a small company in Asheville, N.C., provides technical services to efforts by the Voice of America to get e-mail newsletters into China, using spammers' techniques like altering subject lines or inserting odd characters in key terms (like "June{tilde}4,'' the date of the crackdown on protests in Tiananmen Square in 1989).
......
Dynaweb, an "anonymizing'' service that makes it hard for Chinese servers to identify users, was introduced six months ago by Dynamic Internet Technology and is available at dwang.orgdns.org. That site is more difficult for China to block because while its Web address remains the same, its numerical Internet Protocol address (which the government often uses to identify sites to block) changes regularly.

Dynaweb is seeking money from foundations to promote its service. "We actually hope we can have one full-time programmer to maintain it," said the 29-year-old Chinese immigrant who runs Dynamic Internet Technology and goes by the name Bill Dong.

Bill Dong, spokesman for Dynamic Internet Technology, a company providing technical services to Voice of America's Chinese-language Web site, said keyword filtering had not replaced the block on previously banned sites, but had been added as an extra layer to selectively screen content on other sites.

"This is a way to get more extensive blocking without offending too many people," he said. "There is a Chinese saying, 'govern by separating'. So now, they do not have to block all of Google and offend everybody. They can block the Falun Gong part of a university site, for example, without offending students who need to get information there. So this will make their blocking socially easier."

"... technologies and products, including Peek-a-Booty, DynaWeb, and Freenet-China (the latter a peer-to-peer network), are also currently in use to help keep information flowing in and out of areas where Internet censorship and jamming are prevalent. ..."
